用法說明

FeatureLayer.url函數(或屬性)的定義如下：

url String

圖層、非空間表或服務的 REST 端點的絕對 URL。 URL 可能指向ArcGIS Enterprise 或ArcGIS Online 上的資源。

如果 url 直接指向服務，則必須在 layerId 屬性中指定圖層。如果沒有給出layerId，那麽將加載服務中的第一層。

例子：

// Hosted Feature Service on ArcGIS Online
layer.url = "http://services.arcgis.com/V6ZHFr6zdgNZuVG0/arcgis/rest/services/origins/FeatureServer/0";

// Layer from Map Service on ArcGIS Server
layer.url = "http://sampleserver6.arcgisonline.com/arcgis/rest/services/Census/MapServer/2";

// Can also be used if URL points to service and not layer
const layer = new FeatureLayer({
  // Notice that the url doesn't end with /2
  url: "http://services.arcgis.com/V6ZHFr6zdgNZuVG0/arcgis/rest/services/MonterreyBayCanyon_WFL/FeatureServer",
  layerId: 2
});

// Non-spatial table in San Francisco incidents service.
const table = new FeatureLayer({
  url: "https://sampleserver6.arcgisonline.com/arcgis/rest/services/SF311/FeatureServer/1"
});
// table must be loaded so it can be used in the app.
table.load().then(function() {
  // table is loaded. ready to be queried.
});
